ABSTRACT:
A catalyst useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) is disclosed. The catalyst includes an oxide selected from the group containing alumina, zirconia, titania, yttria, silica, niobia, and vanadia. The catalyst does not contain any unoxidized metals; it is activated by higher preheat temperatures. As a result, similar conversions are achieved at a considerably lower cost.
